(1) Creepage and clearance requirements should be applied according to the specific equipment isolation standards of an application. Careshould be taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the isolator onthe printed-circuit board do not reduce this distance. Creepage and clearance on a printed-circuit board become equal in certain cases.Techniques such as inserting grooves, ribs, or both on a printed-circuit board are used to help increase these specifications.
(2) Testing is carried out in air or oil to determine the intrinsic surge immunity of the isolation barrier.
(3) Apparent charge is electrical discharge caused by a partial discharge (pd).
(4) All pins on each side of the barrier tied together creating a two-pin device.
